CH7233163 is a non-covalent ATP competitive inhibitor of EGFR-tyrosine kinase with antitumor activities against tumor with EGFR-Del19/T790M/C797S.
CH7233163 shows potent antitumor activities against tumor with EGFR-Del19/T790M/C797S in vitro. CH7233163 potently inhibits the proliferation of Del19/T790M/C797S_NIH3T3 cells with IC50 of 20 nmol/L. CH7233163 potently and dose-dependently blocks the EGFR phosphorylation in the Del19/T790M/C797S_NIH3T3 cells. CH7233163 can inhibit Del19/T790M/C797S signaling.[1]
Pharmacodynamic study is performed using Del19/T790M/C797S_NIH3T3 xenografted tumors in mice. CH7233163 clearly inhibits EGFR phosphorylation after oral administration and potent tumor regression is observed. CH7233163 has potent therapeutic efficacy against tumors with EGFR-Del19/T790M/C797S in vivo.[1]
